摘要
针对目前国内多采用小尺寸充填管袋进行现场试验的现状,引入一种室内试验方法——小断面土工织物脱水试验,通过对不同脱水材料、初始含水率及土工织物等参数进行组合试验,分析试验数据,采用过滤、脱水效率等试验指标进行评价,获得了初步结果并提出了建设性意见。
Dewatering test of geotextile tubes is used to study the level of satisfaction between the geotextile and the filling fluid. At present, a local test of geotube with small section has been applied. It is the way used for analysing the feasibility of most engineering proiects with geotubes. This paper introduces a method of indoor test, which is named as small section dewatering test with geotextile tubes. Based on dozens of trials that are assembled with several groups such as consisting of different filling fluids, initial water content and geotextile, experimental data are analyzed. The indexes of filtration efficiency and dewatering efficiency are calculated. They are used to evaluate the test effect . Some conclusions have been drawn and some advices have been advanced.
